COLA is Open!

At COLA we believe that making science open will speed up research progress. We’re committed to sharing our data and materials, and endeavour to make sure that all of our studies are fully reproducible.

Below is a list of our open (anonymised) datasets and materials that are available to download. In most cases, R scripts are also available with the data so it’s possible to reproduce our statistical analyses.

If you can’t find the materials you’re looking for here, please Contact us.


  • Investigating multidimensionality of language lateralisation in left and right handed adults: an update on Woodhead et al. 2019. (Woodhead, Thompson, Karlsson & Bishop, 2020)

fTCD data from N=31 left handed and N=43 right handed neurotypical, English-speaking adults, in two sessions (test-retest). Analyses involved Structural Equation Modelling, and run in R Studio.

There were six tasks: list generation, phonological decision, semantic decision, sentence generation, sentence comprehension and syntactic decision. Tasks were coded in Psychtoolbox, and run in Matlab.


  • Measurement of language laterality using functional transcranial Doppler ultrasound: a comparison of different tasks. (Woodhead, Rutherford & Bishop, 2018)

fTCD data from N=31 neurotypical, English-speaking adults. Analyses run in R Studio.

There were three speech production tasks: list generation, word generation and sentence generation. Tasks were coded in Psychtoolbox, and run in Matlab.


  • Investigating the effects of handedness on the consistency of lateralisation for speech production and semantic processing tasks using functional transcranial Doppler sonography. (Bruckert et al., 2020)

fTCD data from N=151 (21 left handed) neurotypical, English-speaking adults. Analyses run in R Studio.

There were two tasks: word generation (verbal fluency) and semantic association (pictorial Pyramids and Palm Trees). Task materials are not available for this project.


  • Cerebral laterality for the generation of silent and written language in male and female right- and left- handers: A functional transcranial Doppler ultrasound study. (Kondyli, Stathopoulou, Badcock & Papadatou-Pastou, 2017)

fTCD data from N=60 (30 left handed) neurotypical, Greek-speaking adults. Analyses run in DopOSCCI and SPSS.

There were two tasks: oral word generation and written word generation.


  • Cerebral laterality for writing in right- and left-handers: A functional transcranial Doppler ultrasound study. (Papadatou et al, 2020)

fTCD data from N=54 (23 left handed) neurotypical, Greek-speaking adults. Analyses run in DopOSCCI 3.1.6, R studio and SPSS

There were two tasks: written word generation and copying of symbols.


  • Investigation into inconsistent lateralisation of language functions as a potential risk factor for language impairment. (Bradshaw et al, 2020)

fTCD and neuropsychological testing data from N=67 adults with a developmental disorder affecting language, and N=37 neurotypical controls. Analyses run in R Studio.

There were three fTCD tasks: phonological decision, semantic decision and sentence generation.


  • Assessing the reliability of an online behavioural laterality battery: A pre-registered study. (Parker et al, 2020)

Online testing data using a battery of lateralisation tasks and other measures of language ability and handedness. Tasks were performed on two separate sessions. N=392 participants (133 left handed).

Lateralisation tasks (available on Gorilla) were: dichotic listening, chimeric faces, rhyme decision visual half field, and finger tapping.
